Travelnets are no longer diggable since the 5.3 update, they now have a button to remove them. But travelnets placed before the update don’t have that button. If the network has more than one travelnet, you can use the move up/down buttons and the remove button will appear. If there was only one travelnet in the network, add second travelnet in the network and then use the up/down buttons in the old travelnet.
You’re welcome to add those information into our wiki! (Including a tutorial how to use travelnets )
